The project involved the expansion of the Village’s existing wastewater treatment lagoon. New 4,900 m3 facultative and 24,000 m3 storage cells were constructed, complete with clay liners, control structures, valves, erosion control bank protection and replacement outfall. Also included were an upgraded access road and rehabilitation of the existing cells. An additional 4.54 ha area required for the expansion was added to the lagoon facility footprint. The project provides additional wastewater storage and treatment capacity to meet the Village of Arrowwood’s present needs and for future new development.
